In the case that we want to build upon our profile discrepancy heuristic, I think it makes sense to pass in a reference to "something" (variable, struct) that maintains information related to the heuristic, similarly how to the flow function is treated by this function. But I don't have strong feelings about this - if you do I'm happy to change it.
